ARTHUR C. GILLEY, OF WHITE, SOUTH DAKOTA WINDMILL Application filed July 10, 192 Serial No. 377,209.

This invention relates to a windmill, the tudinally extending bore 2 therein through general object of the invention being to prowhich passes a shaft 3, the bore forming a vide the mill with one or more horizontally bearing for the shaft, and a vertically ararranged wind wheels and a substantially ranged elongated hub 4 is fastened to the upsemi-circular hood rotatably supported on per end of the shaft. One or more sets of the tower of the mill and which, when in one blades 5 radiate from the hub 41:, the sets being position, will cover the forwardly moving superimposed, with the blades of one set alblades of the wheel or wheels, so as to preternately arranged with those of the other set. vent the wind from contacting said blades A sleeve 6 is rotatably mounted on the upis while the wind is acting on the other blades right 1 and the main vane 7 is carried by this and when moved to another position, the sleeve.

When the windmill is to'be shut down, it is simply necessary to lower the lever, which pulls the collar downwardly, and this movement of the collar will move the small vane against the large vane through the action of the bell crank and the connections shown and thus the hood will be placed in front of the wheels to prevent the wind reaching the wheels. As before stated, any number of wheels or sets of blades can be used.

It is thought from the foregoing descri'p tion that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made inthe construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What I claim is 2-- A windmill including a horizontally arranged wheel and a support,'a'n inner sleeve mounted on the support andhaving a wheel journalled thereon, anouter sleeve j ournalled on the inner sleeve, pairs of oppositely disposed and connected arm's journalled on the inner sleeve between the outer sleeve and the wheel, a semi-circular shield carried by certain ones of said arms and positioned to receive a portion of the wheeltl'le'rei'n, a main vane secured to the outer sleeve, a stop on one of the arms, and tension means between one of the arms and the vane to normally urge the stopjagainst the vane, an auxiliaryvane secured to one of the arms, and a control having a portion thereof splined to the outer sleeve and connected to the auxiliary'vane for moving the latter'relative to the main vane for controlling the operation of the wheel. 7 i
